Abstract
The utility model discloses a heavy load wearproof dual inner sleeve bearing. The bearing comprises an outer sleeve, an inner right sleeve and an inner left sleeve, wherein an outer groove is formed at the inner side of the outer sleeve, a right inner groove is formed in the outer side of the inner right sleeve, a right boss is arranged on the inner right sleeve, a left inner groove is formed in the outer side the inner left sleeve, a left boss is arranged on the inner left sleeve, the left boss and the right boss are matched for installation, the left inner groove and the right inner groove constitute an inner ring groove, and a plurality of steel balls are installed between the inner ring groove and the outer groove. The bearing can effectively improve the bearing capacity, prolong the service life, and save the maintenance cost of mechanical equipment.
Description
[technical field]
The utility model relates to the technical field of bearing, particularly the technical field of wear-resisting pair of inner sleeve bearing of a kind of heavy duty.
[background technique]
Traditional bearing mainly comprises inner ring, outer ring, rolling element (steel ball or roller) and retainer, because need certain fit up gap in assembly process, so the steel ball quantity packing on a bearing is restricted, camber line distance on bearing between steel ball is larger, between steel ball, have very large neutral gear, bearing often only has indivedual steel balls to bear pressure in the process of work, and steel ball is easily out of shape, easily wearing and tearing, the life-span of bearing can shorten greatly.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, wear-resisting pair of inner sleeve bearing of a kind of heavy duty proposed, bearing with respect to traditional equal size can pack more steel ball into, the anti-pressure ability of bearing is greatly improved, steel ball is more wear-resisting, has greatly improved the working life of bearing.
For achieving the above object, the utility model proposes wear-resisting pair of inner sleeve bearing of a kind of heavy duty, comprise overcoat, interior right cover and interior left cover, there is outer groove the inner side of described overcoat, and there is right inside groove in the outside of described interior right cover, the interior right side has put right boss, there is left inside groove in the outside of described interior left cover, and an interior left side has put left boss, and described left boss and right boss coordinate to be installed, described left inside groove and right inside groove form inner groove ditch, between described inner groove ditch and outer groove, some steel balls are installed.
As preferably, on described left boss, there is left boss hole, on described right boss, there is right boss hole, left boss hole coordinates installation with right boss by pin.
As preferably, described left boss hole is through hole, and described right boss hole is slotted eye.
As preferably, the diameter of described pin is 1～4mm, and the quantity of pin is 6.
The beneficial effects of the utility model: the utility model is by changing an inner ring of existing bearing into two inner rings, in assembly process, can pack more steel ball into, improved the anti-pressure ability of bearing, reduce steel ball and inner ring and outer ring frictional strength simultaneously, effectively extended the working life of bearing.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]

In figure: right cover, the right inside groove of 21-, the right boss of 22-, the right boss hole of 23-, the interior left cover of 3-, the left boss of 31-, the left boss hole of 32-, the left inside groove of 33-, 4-steel ball, 5-pin, 6-inner groove ditch in 1-overcoat, the outer groove of 11-, 2-.
[embodiment]
Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, wear-resisting pair of inner sleeve bearing of a kind of heavy duty of the utility model, comprise overcoat 1, interior right cover 2 and interior left cover 3, there is outer groove 11 inner side of described overcoat 1, there is right inside groove 21 in the outside of described interior right cover 2, on interior right cover 2, there is right boss 22, there is left inside groove 33 in the outside of described interior left cover 3, on interior left cover 3, there is left boss 31, described left boss 31 and right boss 22 coordinate to be installed, described left inside groove 33 and right inside groove 21 form inner groove ditch 6, and some steel balls 4 are installed between described inner groove ditch 6 and outer groove 11.On described left boss 31, have left boss hole 32, on described right boss 22, have right boss hole 23, left boss hole 32 coordinates installation with right boss 22 by pin 5.Described left boss hole 32 is through holes, and described right boss hole 23 is slotted eye.The diameter of described pin 5 is 1～4mm, and the quantity of pin 5 is 6.
Wear-resisting pair of inner sleeve bearing of a kind of heavy duty of the utility model, by to the inner ring of bearing from new design, in bearing, can proceed to more steel ball 4, thereby disperseed the pressure in working procedure, make more steel ball 4 simultaneously stressed, effectively reduce the distortion of steel ball 4, reduced the wearing and tearing of steel ball 4, thereby increased the working life of bearing.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
